--------------------------------
When I drag and drop this control it gives me error "Error parsing the template" in sitefinity backend editor. And I dont get any testimonial binded in telerik:RadListView. I just get "<h1>Testimonials</h1>" in output.

When I debug below lines, I found "list"  contains true data. but it doesn't show in RadListView.

System.Collections.Generic.List<Testimonial> list = query.ToList();
 this.TestimonialsListControl.DataSource = list;


Where I am doing wrong?

I am having the exact same problem. I have triple checked - the controls Build Action is set as "Embedded Resource" but I still get the same Error parsing the template error.
Also the VirtualPath settings seem to be fine:
Here's my path in the MasterListView.cs

Hi Vaibhavi,

Did you try removing the following parts from your Register clauses:

", Version=4.2.1733.0, Culture=neutral, PublicKeyToken=b28c218413bdf563"

and leave just the name of the assembly.

I do not have the versions in my registry clauses and Ive even modifed my MasterListView.cs to the code below, still I get the same error.

I tried removing the ", Version=4.2.1733.0, Culture=neutral, PublicKeyToken=b28c218413bdf563" but getting same error.

Hi Vaibhavi,

I attached a small class library project that uses your control and its template. You also need to fix the references, add a reference to this control from your main SitefinityWebApp and add the following virtual path setting:

VirtualPath - "~/CustomWidgets/*"
ResourceLocation - "CustomWidgets"
ResolverName - "EmbeddedResourceResolver"

This setup was working for me and I got no error.
